Interesting question and one which I've since played back to a few people who all seem to agree that the general approach is to either "bumble along" or to "wing it"! Clearly there must be a better way to really excel in these important areas of our life!
Amazing, but since then, I have come across 2 people in my network who have parenting businesses - Erin Kurt at Erinparenting.com and Kerri Summers at TheParentCompany.co.uk and another one is planning on starting one up. I also have a university friend, Bruce Sellery, who has written a book and has a personal finances business - moolala.ca Why smart people do dumb things with their money.
Finally, I've also been so encouraged by all the positive feedback and support I've received thus far. Here's to upskilling in areas of our life that mean so much to us!
